Managing personal Outlook.com account settings, security, and privacy
Hello Helia,
The email code prompt does not necessarily mean that two-step verification is enabled. Even when it is turned off, Microsoft may occasionally request an additional security code if a sign-in is considered unusual or requires extra verification. This can be assessed separately for each account, which may explain why only two of your four accounts are affected.
Please check the Recent activity page for each account and review whether there are any sign-ins you do not recognize: Review recent account activity
It would also be a good idea to add more than one backup sign-in method under Security > Manage how I sign in, such as Microsoft Authenticator, a passkey, or another accessible recovery email: Manage your Microsoft account security information
The “Remember this PC” option may not always appear. Also, if browser cookies are being cleared, blocked, or the account is accessed through an InPrivate window, Microsoft may not be able to retain the trusted sign-in session.
If the same two accounts continue requesting a code on every sign-in from the same browser and device, even with cookies enabled, you can contact Microsoft Support so the sign-in behavior can be investigated further.
Please note that this is a user-to-user support forum. Contributors do not have access to account security records or Microsoft’s back-end sign-in systems. Thank you so much for your understanding.
